Should You Never Apply Sealant When Replacing the Valve Cover?

Can sealant be applied when replacing the valve cover? Below are the specific details about the valve cover: 1. Aluminum alloy valve cover: Replacing with an aluminum alloy valve cover can provide better sealing, but it's also necessary to check whether the rubber gasket is aged or damaged during installation. If the gasket is aged and not replaced, even switching to an aluminum alloy valve cover won't completely solve the problem. You can use certain engine oils that help soften the gasket, as softening the gasket can enhance the valve cover's sealing. 2. Sealant application: After replacing the gasket, oil leakage issues can be resolved, making sealant application unnecessary. If oil leakage persists after gasket replacement, sealant can be applied to improve the valve cover's sealing, or the valve cover can be replaced altogether. 3. Function of the valve cover: The main function of the valve cover is to protect the engine's camshaft, while also forming a nearly enclosed cavity together with the cylinder head. Inside, there are oil return and supply passages connected to the cavity.

What Causes the Abnormal Noise When Turning the Car Key?

There is an issue with the ignition switch. The rear part of the car key is connected to a circular circuit switch, which rotates when the key is turned to connect the circuit (sequentially activating the audio system, the entire vehicle circuit, and the starter motor). When the switch has poor contact, sparks occur along with a squeaking noise. The solution is to remove and replace or repair this switch. Related details are as follows: 1. When the ignition switch is in the "OFF" position: When the key is turned to the "OFF" position, the two contacts in the horizontal position are connected, which means the external wires "white-black wire" and "green wire" are connected. If you measure these two wires with an ohmmeter (Ω setting) at this time, they should show continuity. In the actual vehicle, the connection of these two wires indicates that the entire vehicle's electrical system is shut down, and the ignition system circuit is in a short-circuited state, causing the engine to stop. 2. When the ignition switch is in the "ON" position: When the key is turned to the "ON" position, the two contacts in the horizontal position are connected, which means the external wires "red wire" and "black wire" are connected. If you measure these two wires with an ohmmeter (Ω setting) at this time, they should also show continuity. In the actual vehicle, the connection of the red and black wires indicates that the signal system is activated, and the signal circuit is ready to operate at any time.

Why Does Car Glass Frost Up in Winter?

It is due to the temperature difference between the inside and outside of the car. Because the temperature inside the cabin is higher than outside, the moisture in the cabin condenses on the inner windshield, forming frost. When the moisture in the warm air approaches the cold glass, it cools down and condenses into frost on the glass. Here are some solutions: 1. Defogging function: You can use the car's air conditioning defogging function to remove it. 2. Using the air conditioner: In this case, it is recommended to turn on the air conditioner first, use the cold air for a while, and then switch to warm air after the fog dissipates. Adjust the air conditioner to blow directly at the windshield, so the warm air can evaporate the fog. Alternatively, wiping the inside of the windshield with a cloth dipped in detergent or a special anti-fog agent can also effectively prevent fogging. While driving, you can slightly open the window to prevent fogging.

What Causes Airbags Not to Deploy?

Airbags not deploying does not necessarily indicate damage. It could also be because the conditions for airbag deployment were not met. Minor collisions will not trigger airbag deployment. Airbags are a passive safety system device. When a car collision occurs, the pressure sensors in the airbag system and the acceleration sensors in the ECU assess the collision. If the conditions for airbag deployment are met, both will receive signals simultaneously, causing the airbag to inflate instantly and protect the driver's head and chest, thereby ensuring personal safety. Necessary conditions for airbag deployment: 1. Vehicle speed: Generally above 50 km/h, but the key factor is the acceleration during the collision. In national certification tests, the instantaneous acceleration during collision is approximately -40g. 2. Frontal collision: The impact angle must be within approximately 60° of the front. 3. Collision object: Rigid walls or obstacles; airbags will not deploy when a car collides with soft objects at 80 km/h.

When to Use the M Gear?

The M gear can be used when going uphill or downhill, as well as when needing to overtake quickly. The M gear is a feature found in many cars equipped with automatic transmissions. The M gear stands for manual mode, and once engaged, the driver can manually control the transmission to shift up or down. Some sportier models even come with paddle shifters on the steering wheel, allowing the driver to shift gears directly using the paddles after switching to manual mode. Some automatic transmissions respond relatively slowly. If you need to overtake quickly, the transmission usually takes some time to downshift after pressing the accelerator pedal. In such cases, switching to manual mode to downshift allows the car's power to be unleashed much faster. When descending long slopes, relying solely on the braking system to slow down can easily lead to overheating and failure of the brakes, which is very dangerous. In these situations, using manual mode to keep the transmission in a lower gear allows the car to utilize engine braking to slow down. In addition to the M gear, automatic transmission cars also have other gear positions marked with letters such as P, R, N, D, S, and L. Below is a detailed introduction: The P gear stands for Parking, R for Reverse, N for Neutral, D for Drive, S for Sport, L for Low, and M for Manual. Different gear combinations output varying levels of power. When the car is moving at different speeds, it needs to "shift gears," meaning selecting different gear combinations to output power. P Gear: Parking means "to park." It is used when parking the car. After reaching your destination or when parking for an extended period, shift the gear lever into this position. Note: The vehicle must be completely stopped before shifting into P gear. Shifting into P gear before the car has fully stopped can damage parts of the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the car from moving forward or backward. Therefore, always engage P gear when parking on an incline. Additionally, during short stops (e.g., at traffic lights), it's best not to shift into P gear to avoid severe damage to the transmission in case of a rear-end collision. R Gear: Reverse means "to go backward." It is used when reversing the car. To engage reverse, press the safety button on the gear lever. However, ensure the vehicle is completely stopped before shifting to avoid serious damage to the transmission. N Gear: Neutral means "in the middle." It is also known as the neutral gear. At traffic lights, you can shift into this gear and press the brake pedal. If the wait is longer, it's advisable to engage the handbrake, allowing your foot to rest off the brake pedal. A common misconception is that shifting into N gear while coasting downhill or at high speeds saves fuel. This is a serious mistake—it not only doesn't save fuel but can also damage the transmission. D Gear: Drive means "to move forward." It is the forward gear in a car. Shifting into this gear and pressing the accelerator allows the car to move. In this gear, the transmission automatically shifts based on speed and throttle input. At traffic lights, you can stay in D gear while pressing the brake. If the wait is short, this is fine, but prolonged stops in D gear can raise the transmission fluid temperature and degrade the oil. S Gear: Sport means "athletic." In a car, it stands for Sport mode. When engaged, the transmission delays shifting to provide more power, typically used when overtaking. L Gear: Low means "slow." In a car, it stands for Low gear. When engaged, the transmission operates only in low gear (equivalent to first gear in a manual transmission) and does not shift automatically based on speed. This gear is generally used when climbing or descending steep slopes. In low gear, the drive wheels output higher torque, providing sufficient power to climb steep inclines. Prolonged braking can overheat the brake pads, reducing braking efficiency, which is dangerous on long or steep descents. In such cases, shifting into L gear uses the engine's low RPM to control the car's speed, eliminating the need for constant braking.
